Michael Armbrust commented on SPARK-2973: ----------------------------------------- I think the confusion there would be if someone then run .map(...) on that RDD. It would be pretty confusing if it did not run a Spark job. What is wrong with the approach we are already using for executeCollect(). We can add a executeTake with a default implementation and override that in ExecutedCommand. > Add a way to show tables without executing a job > ------------------------------------------------ > > Key: SPARK-2973 > URL: https://issues.apache.org/jira/browse/SPARK-2973 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Aaron Davidson > Assignee: Cheng Lian > Priority: Critical > Fix For: 1.2.0 > > > Right now, sql("show tables").collect() will start a Spark job which shows up > in the UI. There should be a way to get these without this step. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
